This is a hack for OpenCL, and is not meant to work otherwise, it should only be used for OCL (looks like an unfortunate import from some brainrot we put in AMDGPU). We've made an effort to fix this recently, so perhaps we could look at moving SPIR-V away from it as well, see #112442 and its children.
